SHIP- SALVAGE 'nnvrcn To all whom 'it may concern:

Be it known that I, KAZIMIRZ GALEsxI, a citizen of Poland, residing at Harrah, county Yof Oklahoma, andv State of Oklahoma, have invented certain new and useful Improvements in Ship-Salvage Devices, of which the following is a specification.

VThis invention relates to a device for raising and salvaging sunken ships and it has for an object to provide a simple arrangement whereby an adequate lifting power may be exerted and the ship safely supported when raised as long as may be desired either for repairs or otherwise.

A further object is to provide a device of this kind which will constitute in elfect a closed dock in which the ships'may be contained and which may be opened when de? sired to permit of the passage ,of the ship therefrom.

For further comprehension of the invention, and of vthe objects and advantages thereof reference will be had to the following description and accompanying drawings, and to the appended claim in which the various novel features of the invention are more particularly set forth.

Figure 1 of the drawings is a side elevation of the device showing it connected to a sunken ship to raise the latter.

Fig. 2 is a plan view of the larger scale.

Fig. 3 is an end view thereof.

Fig. 4 is a transverse vertical section on the line 4--4 of Fig. 2.

As shown in the drawings my ship raising and salvaging device comprises a hollow rectangular pontoon or float made up of two sections or halves consisting of the main side members 1 and 2 from the ends of which the inward offsets 1 and 2 project toward one another, their end faces meeting device on a in the median line of the pontoon, the offset members at one end being hinged together as at 3 so as to enable the two halves or sections to swing apart. The offset members at the opposite end of the pontoon are locked together by suitable releasable locking means which here consists of a series of pins 4 projecting rigidly from the offset 2 and projecting into suitable apertures in a Y Specification of Letters Patent.

ing 'therewith a pinion 8 on a vertical: stub shaft 9 suitably'journaled on the'top ofthe pontoon and provided with a handle wheel Patented Sept. l14, 1920.

Application led December 30, 1919. Serial No. 348,269.

space 12 within the members thereof, into which opening the ship is adapted to be drawn when raised.

The shipV is adapted to be raised by suitable chains or cables which are secured thereto or passed around the bottom thereof by divers let down from the pontoon, these cables being connected to winding devices on the pontoon. As here shown there are a series of four of these winding devices located on the pontoon adjacent the four corners of the central space or opening. AV

pair of cables 13 and 14 may thus be passed under the front and rear ends of the ship as indicated in Fig. 1 where the ship is shown at 15 suspended in the cables, whose ends are connected to thewinding devices on opposite halves or sections of the pontoon.

These winding devices each comprises a `drum 16 journaled in brackets 17 on the pontoon and each having a gear 18 fixed on one end of the drum shaft, which gear is engaged by a pinion 19 on the shaft of an electric motor 20. The opposite end of each drum shaft has fixed thereto a ratchet wheelr over these pulleys and secured to and wound upon the drums. Itis to be understood of course that the pontoon will be equippedy with suitable means for supplying power to the motors 20.

In use the pontoon is positioned over the sunken ship with the bow of the ship toward the end thereof which is adapted to open. The cables 13 and 14 are then attached to the ship and the motors are then started,

causing the cables to wind upon the drums. and raise the ship. When raised, repairs can be made to the ship suiiicient to allow it to be lioated out of the pontoon the two .Y

halves being swung apart on the hinges 3 to permit of the ship passing out of the inclosed space.

VHaving thus described my invention What I claim asneW and desire to secure by Letters Patent, of the United States is as folloWs- A ship raising device comprising a rectangular pontoon separated along its medianline into two sections and'rinclosing a rectangular space, said sections being hinged together at one end, releasable means locking the other ends of the* sections together,

said means comprising brackets on said sections, a vertical shaft journaled in said brackets, a series of arms fixed to said shaft and provided With apertures, a series of pins adapted to engage the apertures of said arm, a spur gear on said shaft, and a pinion in mesh with said spur gear and adapted to be operated byv a hand-Wheel on the vertical stub shaft on said pinion, and means adapt-` ed to raise the ship into the said space.

In testimony whereof I have affixed my signature. v KAZIMIRZ GALESKI.
